With the Labour leadership election less than a week away, BBC deputy political editor John Pienaar asks if Labour is on the brink of self-destruction. Panorama spent the summer in Brighton, on the frontline for the battle for the soul of Labour, where local activists slog it out for control of the party. In one corner, Momentum fights off ugly allegations of bullying, anti-Semitism and hard-left entryism. In the other, the party's 'moderates' fear election annihilation and deselection. The programme follows both sides through the ups and downs of the campaign and finds neither side in the mood for compromise.
